When I moved into my present house at the end of 2003, apart from the lawn, there was only one laundry line in my backyard. As I enjoy plants and flowers, I paid a high price to put in landscaping. Unfortuantely it seems that our household is the only one which enjoys having a garden around here. My neighbour on the left, a retiree, keeps a few trees and a few low maintenance plants that hardly make a garden. But he at least keeps his backyard tidy and neat. My neighbour on the right has a big swimming pool which covers almost 95% of the space in the backyard. About 4% of the remaining space is concrete. In the 1% space around the fence he grows some climbers, so there is some green. In between his backyard and mine there are a few unknown medium sized trees that hang over both his and my sides. My neighbour at the back has one gigantic maple tree (about double the height of my house) in the middle of his backyard with a crabapple tree by its side. The maple tree leans towards our house and overshadows about 2/3 of my garden. This neighbour at the back is an elderly men and he grows nothing but weeds! His neighbour on his left also grows no flowers. Not only that, that household has two strong teenaged sons who always practise soccer in their backyard and they very rarely mow their lawn. Their backyard is also an exhibition ground for a large variety of weeds. Come autumn, I am raking all the leaves of my neighbours' trees. Come spring, come summer, while I work diligently to maintain a respectable garden, my neighbour's weed seeds are blown over to our backyard; the gigantic maple will shower a million keys on our side, and to join the fun, the unknown trees will give us another million blueblack berries (not edible) which are a big mess and which stain everything blueblack. The worst is yet to come - before I can rake up or clean up the mess brought by the maple keys and the berries, they germinate into a million seedlings all over the place. I find myself forever fighting a lost battle of weeding and pulling unwanted seedlings out from everywhere. I feel so weary and frustrated. Does anyone have a solution or suggestion for me to get rid of this agony?
